This awesome isolated, singular boulder hill appears as a gigantic monolith rising at a height of 700’ is aptly connected with a popular mythical tale of immortality in Hindu Puranas.

Close to the Vidyapeeth railway station, about 50 km. from the main city of Bhagalpur, Mandar hill is a sacred destination to Jains and Hindus both. At the base of the hill a large tank having a Vishnu temple at the centre with a lotus structure is built in the recent past. In the memory of the 12th Jain Tirthankara Vasupujya who attained nirvana here, a temple is built on top of this hill. On the way to the top an astounding lake settled at the niche of the black rock is absolutely startling.

The mythological tale of Hindus describes this hill as Sumeru Parvat, the churning pole of Amrit Manthan (Nectar of Immortality) with the winding ‘Naag’ (the Great Snake). The patterns that are visible on the rock is believed to have created by the mythical Great Snake while the churning took place between the Devs and Asuras.
The Baunsi annual fair is a popular one to draw a lot of tourists at the place.
